same parts in. all of the views: Figure '1 V is an elevation of the extensible clamping sections of the binder in a partly open position. parts being broken away and other parts in section, and fragments of the cover hinge leaves also being shown; Fig. 2 a transverse section thereof taken on line 2 2 1 modified form of binder provided with two covers and extensible bael: clamping sections are arranged to be moved toward and away from each other and are provided with telescoping posts which are adapted to engage and hold in locked position. loose leaves in sertcd between the covers and extensible sections. j

()ne of the objects of the invention is to provide a loose leaf binder in which the toggles which draw the sections together are so pivoted and positioned with relation to the sections and the clamping screw that the.

pawls; F L is an elevation of another modified form; parts broken away to'sliow interior construction; Fig. 5 is a trans versc sectional view taken through the telescoping tubes of the binder shown in Fig. 4; Fig. 6

A further object ot the. invention is to provide means whereby when the binder is unlocked the extensible sections will automatically open; and when in an open position the sections may be closed .by a direct. pressure thereon and when pressed the sections will be automatically held in locked posi-.

tions of adjustment. A still further object of the invention is to provide means whereby the hinged covers are permitted to yield or give under strain outwardly at thehinge joints to provide 'for the bulging 'outwardly otthe leaves at this point. I

A. still further object ofthe invention is to provide a' binder in which the working. partsare almost entirely inclosed and made practically dust proof thus prolonging the wear of the working parts.

A still further object of the invention is to provide attaching means whereby the binder is convertiblcfroin, an ordinary clock key operating and locking means to a Yale key operating and locking means thereby obviating the necessity of the manufacturer carrying two kinds of binders in stock.

With the above and other objects in view the invention consists of the devices and parts, ortheir equivalents.

In the accompanying drawing in which the saitrereternce characters indicate the thereto.

11- 11 of Fig. 10. i

Referring to the drawings the numeral 8 indicates the back of the binder and 9 the extensible back sections slidablyconnected These extensible. SQGUOHS are formed of sheet metal Hat on the back and with heirouter ends bent over to form sen icircular portions 10 and again bent at right angles to the back to form flanges 11 to i which telescoping posts 12 are connected. The semicircular portions of the extensible sections are provided with slots 13 through which U-shaped shouldered hinge clips 1-1 project andcovers 15 are hinged thereto by nieansof hinge pins 16 passing through the loops or eyes of the clips, and also through eyes provided in the cover. The shoulders 17 of the hinge clips'prevent their withdrawal outwardly from the slots and the connection of said clips to the sections permits them to yield or swing outwardly from the extensible back sections to accommodate the bulging of the leaves just beyond the point of clamping engagement of the extensible back sections with s'aid'leaves.

The extensible back sections are provided with end portions 18 rigidly connected thereto, and these back end portions areadapted to slide "in the angular shaped grooves 19 formed in the end portions 20 of the back 8.

The threaded clamping screw 21 is in'ounted'in bearings 22 connected to the inner surface of the back 8 and is held from endwise movement hy the sahoulders 23 formed hy the hall hearing cup The hall hearing 5 portions of a hearingplate 26 :lastencd to the inner surface of the hack 8.

A chambered slidahle memher surrounds the clamping screv-i 21, and is provided with guide openings 28 throughwaich the (fltlll'lplllg screw tr cly extends. .29 threaded to the damping screw and positioned within the chainher ot the slidahle member is provided with a pivoted spring actuated pawl 30 which is adapted to normally engage the ratchet teeth formed on the slidahle member within the chamher. The pawl and ratchet teeth are so positioned A nut E with relation to each other that in turning 1 the clamping screw to draw the cover sections together the nut wil he unmov: hlv

heh with relation to the slidahle niemherrhut it it is desired to partly close the hook by dr rect i u'essure on the cover sections, the pawl will slide over the ratchet teeth and hold the cover sections in adjusted positions and a still greater clanu'iing eti'ect may then he given the cover sections by turning the clan'uiing screw. The tree end. 32 ot the pawl is beveled oti at an angle and is adapted to he engaged by a conical unlocking neuiher 33 connected to the elauiping screw 21 when it is desired to disconnect the pawl from the ratchet teeth in order to quickly open the hinder, this result. heing accolnplished hy uns rewing the clamping screw until the conical t ace of the unlocking incinher engages the heveled free end of the pawl and moves it outwardly and the other end of the pawl inwardly to disconnect it from the teeth of the ratchet. A coiled spring 34 having one end connected to the slidahle member and the other end to the binder hack is adapted to automatically open the cove sections when released by the pawl and nut.

T runnions or extensions 35 on which are pivotally mounted pairs of links 36 project from the slidable memher and holding screws 37' threaded therein and provided;

with leather 45 or other desu'ahle hindmg with washers bear against the outer link and hold the links from working off of the ends of the trunnions; The trunnions are i of such length that when the holding screws are screwed home sutlicient space is provided between the washers andthe nuts to permit the free turning of the links on the trunnions.

The other ends of the links are pivotally connected to the inner surface of the flat portions of the extensible hacks by rivets forming a t gg'le jointconnection between the cxtensihle hacks and the clamping screw whereby when the clamping screw is turned in one direction on the not the slidahle meniher will be ad vanced' therewith and the extensible hacks will be moved into clamping engagement with the leaves inserted l l l l l i 1 therehetween, and when the clampin screw is turned inthe opposite direction the slidahlo memhcr will he drawn in the opposite dircction hy the coiled spring and when the pawl is engaged by the unlocking melnhcr the e\' tensihle hael-ts will open outwardly tor the insertion(ii-removalot'leaves. lhetlatportions oi the extensiole hacks are raisitionta s that their inner ed es will hutti against ea 'h other when in a closed position and when in this position they serve to form a du t tight inclosure in which the clamping screw is positioned, pm'tions ot the exh-nsihlr harks heing cut away to provide openings it) for the trunnions to i'oject therethrough For engagement with the toggle links.

One end f the clampinef screw rod 21 is provided with a squared end it) and a slotted extension rod l1 provided with a squared hole adapted to engage the squared end ot the screw rod. The enlarged slotted end of the extension rod =11 extends through an opening 42 provided in one of the ends 20 and into an escuteheon plate 1?). The outeheon plate is riveted to the end 20 over the opening {t2 and provided with a revoluhle key-hole disk 4-1 mounted there in. The lx'QYdlOlB in the disk is torn'ied to correspond with the shape. of the cros section of the key used so that in inanu'taetim ing it is only necessary to change the disk n the escutcheon plate in order to aeconr niodate different shaped keys, the slot in the extension rod heing as wide as the thickest key used. In some cases it. is dcsirahle to arrange the binder so that an ordinary clock key may he used to lock and unlock the same and to accomplish this result it is only necessary to remove or omit the escuteheon plate and the extension rod and the hinder is then adapted to he operated hy inserting an ordinary clock key through the opening 42 in the end of the hack and engage the squared end of the screw rod in the same manner as it is engaged by the extension rod. Portions of the hack and the extensihle hack sections of the binder are covered material to give the desired finish thereto.

Tn the modified form shown in Fig. 3, two ratchet toothed plates to are positioned within the slidahle inenihcr and the clampinc screw nut is provided with two ratchet prwls :lT adapted to engage the teeth of said plates. in other respects the hinder is the same as the form shown in Fill. 1..

In the towns thus far desrrilual the link mnnei'tions with the slidahle inemher t'orm parallel grams and in moving. the links on one side at the hinder are alwa z's parallel -with relation to each other and l.lttt(" lS con sequently n tendency for the hinder sec-- tions to hind in (adenine or chising, hut in the modified forms shown in Figs. 4 to 11 inclusive the i'nedia] pivotal connections of the links are adapted to move toward and away from each other in opening and closing the binder, thus making it necessary to provide guiding means for the slidable members. In these forms the backs of the hinders are provided with elongated slots 48 and the slidable members are "provided with guide pins 49 which are adapted to slide in said slots. I

In the. Fig. 4 modification one pair of links 50 are pivotally connected to a sleeve 51 mounted on the clamping screw 52 between two collars A coiled spring 54 is connected to this sleeve and to the binder back and in connection with the spring 34 serves to spread the extensible sections apart when the pawl is released from the rack 31 connected to the slidable member 55. The links 36 are connected. to the slidable member in the same manner as in the principal form. In this form the end 56 of the clampingv screw is squared for a considerable distance and the slotted extension rod 57 provided with a squared hole is adapted to engage the squared end of the clamping screw to adjust the position of the screw.

.The elongations otthe squared screw end and the squared opening in the extension rod permits the longitudinal movement of the screw without becoming disengaged from the rod. The extensible rod is held in place by means of its reducedportion being engaged by the bearing. 57'.

In the modified form shown in Fig. 10 two slidable blocks are provided and the clamping screw 56 is provided with right and left handed screw threads which are en gaged by nuts 29 positioned within the slidable members. Each of these nuts is provided with two pawls which engage the twin racks 58 with which each slidable memher is provided.

If it is desired to open the binder the operation is as follows: The clamping screw is turned to the left by means of a key ,in sorted in'the key-hole and engaging and turning the extensible, rod, or the screw rod direct it the escutcheon plate and extensible rod are omitted, and this movement Wlll "note the nut and slidable member to the left until the beveled free end of the pawl engages the conical face of the unlocking member. When this engagement takes place the pawl will be disengaged from the rack tceth and the coiled spring connected to the slidable member will move said member and straighten the toggle links and expand or open the extensible sections.

. The operation of the modified form of binder shown in Figs. 10 and 11 is similar to the foregoing with the exception that a plurality of nuts, slidable members, pawls, racks and coiled springs are moved by the turning of the key instead of the single parts shown in the other forms of the invention.

hen in an open position leaves provided with openings and with slots leading there from to the rear edge of the sheets (not shown) and registering with the locking posts, are positioned between the extensible back sections with the openings in register with thepcsts. The clamping screw isthen. turned in the opposite direction until the pawl is released by the unlocking member and again engages the ratchet teeth. The extensible sections are then pressed together to clamp the leaves. During this movement the pawl will slide over the teeth and hold the sections in adjusted positions. The clamping screw is now turned to provide the requisite power to firmly clamp the leaves in position, and when sufficiently clamped so that the leaves are firmly bound in the hinder the key is removed and the binder may be used in theordinary way.

From the foregoing description it will be seen that a binder is-provided which is very desirable and possesses many features of novelty.

By placing the inner pivotal connections of the toggle links in line with the clamping screw and the outer pivotal connections near the outer portions of the back sections the greatest possible leverage is obtained in a construction of this character, and by means of the coiled springs connected to the slidable member, the extensible sections automatically open when the pawl is released from the rack teeth.

The working parts of the binder are practically dust proof when in a closed position i and by means of the provision of the fiexi-" bility of the hinge clip connections the covers are adapted to yield at the hinge joint to compensate for the bulging of the leaves and permit the covers to lie fiat against said leaves.

By means of the novel arrangement of the escutcheon plate and the extension rod the binder is convertible for different styles of keys which is a very desirable feature from a manufacturing point. of view.
